This article lists a chronology of Stanley Cup engravings. A unique feature of the Stanley Cup is that, with few exceptions in the past, it is the only trophy in professional sports that has the name of the winning players, coaches, management, and club staff engraved on it, but this has not always been the case as some teams did not engrave their names on the Cup for unknown reasons (which was rectified with a redesign of the Cup in 1948). When he first donated the Cup in 1892, one of Lord Stanley of Preston's original conditions was that each team could, at their own expense, add a ring on the Cup to commemorate their Cup victory (the first year being an exception). Lord Stanley's original trophy was simply a silver bowl minted with the words "Dominion Hockey Challenge Cup" on one side of the outside rim, and "From Stanley of Preston" with his family's coat of arms on the other side. The format and location of the engravings, including the addition and deletion of extra bands and rings attached to the bottom of Lord Stanley's original cup/bowl, has changed through the years. By its 125th anniversary in 2017, the Stanley Cup had had 3,177 names engraved on it, of which 1,331 belong to players. Challenge Cup Era During the Challenge Cup Era from 1893–1914, the Stanley Cup was a "challenge trophy"; the champions held onto the Cup until they either lost their league title to another club, or a champion from another league issued a formal challenge and subsequently defeated the reigning Cup champion in a special game or series. Teams had to add their names to the trophy at their own expense. Initially, there was only one ring, the one added by the first Cup champion Montreal HC. Clubs then engraved their team names, usually in the form "[TEAM NAME] [YEAR WON]", on that one ring until it was full in 1902. With no room to engrave their names (perhaps unwilling to pay for a second band to the Cup), teams started leaving their mark on the bowl itself. A second ring was finally added by the Ottawa Senators in 1909. As mentioned earlier in this article, some teams during this era did not engrave their names on the Cup. (*) Note: The Winnipeg Victorias engraved "1895" instead of "1896" because they won their Stanley Cup Challenge against
